Answer:
9
Step-by-step explanation:
Distance between two points is given as;
Square root [(X2-x1) 2+ (y2-y1)2]
= (6-(-3))2 +(-4-(-4))2
=Square root (81 +0)
=9

Answer:
y=-½x+1
Step-by-step explanation:
The slope is negative because it goes down from left to right
The y-intercept is ½ because the point where the line meets the y-axis is ½
Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
